From icy cold to burning hot – the thermal shock test at -30 °C causes engine and head gasket to age several years within hours.

Engine test stands The examinations conducted on engine test stands range from straightforward endurance tests to low-temperature thermal shock tests with freely selectable temperatures, loads, and speed gradients. ¬ Nitrogen pressure test: Before and during engine operation, the individual combustion chambers are subjected to internal pressures up to 120 bar using nitrogen. Functionality and sealing potential of the cylinder head gasket is evaluated by monitoring the adjacent combustion chambers and the surrounding coolant channels. ¬ Electronic distortion and roughness measurements on the deck surfaces of engine block and cylinder head, before and after the engine is run. ¬ Measuring the change in bolt force:

Using ultrasonics, the preload of head Bolts can be determined before, during, and after an engine run. ¬ Analysis and evaluation of adjoining Components: Frictional damage, scoring, bead measurement, and surface pressure distribution after the engine test run. Documentation ¬ All test results are summarized and explained in a comprehensive test report. This simplifies and speeds up subsequent fine-tuning with your engine designers and builders.

Quality assurance: Beyond the standards
Series production release

At VICTOR REINZ, we have a name for our quality assurance process – systematic quality. This process provides intelligent quality management for rational zero-error production for production reliability and efficiency beyond the current standards. During the testing phase, we simulate the manufacturing process by using close-to-series tooling. This enables us to test Cylinder head gaskets in close to their final state without delay, complete with a detailed test report and quality certificates for all the materials used, as required for sample approval. Subsequently, we can immediately begin preseries and series production.
